This task, the full details of which were revealed for the first time on Tuesday of this week, when representatives of the technical press were permitted to F 'V.rcraf.t . inspect the work, consisted in designing "dehixe an<^ producing the whole of the struc- tural work for the new 5 million cub. ft. airship R.101, which is being erected at the Royal Airship Works at Cardington. In order to avoid being misunderstood when we say " designing and producing " the structural frame- work, the system followed in dividing the design responsibilities should be made quite clear. Single-line diagrams (diagrams in which each girder or member was represented by a line) were stressed by the Royal Airship Works, and the geometry and loads thus available were used by Boulton and Paul to convert this line diagram into an actual structure. In other words, Cardington said, in effect : " Here is a member of such and such a length, ha^ng such and such a curvature, and to be capable of sustaining such and such a load," and Boulton and Paul then designed the actual built-up girder structure to fulfil the stipulated conditions. It will be realised that the very closest collaboration between the two design staffs was essential, and Mr. J. D. North, Boulton & Paul's chief engineer, was appointed to act as consultant to the Director of Airship Develop- ment. The airship was so designed, as a compromise between perfect aerodynamic shape and practical manufacturing possibilities, that its main longitudinal girders were arcs of circles, varying between one degree and two degrees of arc, and having radii in the neighbourhood of a quarter of a mile. When these arcs are joined together, they actually form a series of different curves which, although not theoretically perfect, approach so closely to the streamline form
